How Screwed is Intel without Hyper-Threading?

How Screwed is Intel without Hyper-Threading?

Corona is a high performance renderer and here the 8700K saw a 31% performance decrease with Hyper-Threading disabled, while the 7700K saw a similar 33% drop off. The 8700K saw a 10-12% performance drop off with Hyper-Threading disabled while the 7700K saw a 24% drop off, though the 1% low margins were similar to what we witnessed with the 8700K. For the games we tested, with a 6-core Intel CPU you will see minimal impact on performance for the most part, though 1% performance does suffer at times and on high refresh rate gaming you’ll notice the performance drop.

100% renewables doesn’t equal zero-carbon energy, and the difference is growing

100% renewables doesn’t equal zero-carbon energy, and the difference is growing

“To guarantee 100 percent emissions reductions from renewable energy, power consumption needs to be matched with renewable generation on an hourly basis,” said Sally Benson, co-author of the paper and co-director of the Precourt Institute for Energy. “In California, gas is often the marginal generation source and has a higher emissions rate than average grid power, which is why purchasing renewables can result in a net negative carbon footprint,” said de Chalendar. By using its energy storage to maximize purchases of electricity in the afternoon when solar power dominates the California grid, Stanford could reduce emissions from heating and cooling by an additional 40 percent, according to a study published earlier this month by the authors of this paper.

These maybe the first images of dogs, and they’re wearing leashes (2017)

These maybe the first images of dogs, and they’re wearing leashes (2017)

And those lines are probably leashes, suggesting that humans mastered the art of training and controlling dogs thousands of years earlier than previously thought. For the past 3 years, Maria Guagnin, an archaeologist at the Max Planck Institute for the Science of Human History in Jena, Germany—in partnership with the Saudi Commission for Tourism & National Heritage—has helped catalog more than 1400 rock art panels containing nearly 7000 animals and humans at Shuwaymis and Jubbah, a more open vista about 200 kilometers north that was once dotted with lakes. The researchers couldn’t directly date the images, but based on the sequence of carving, the weathering of the rock, and the timing of the switch to pastoralism, “The dog art is at least 8000 to 9000 years old,” Guagnin says.

Who Art Thou, Shakespeare?

Who Art Thou, Shakespeare?

(Princeton University Press)
In “How the Classics Made Shakespeare,” Jonathan Bate — provost of Worcester College, Oxford, as well as a scholar of remarkable industry — probes what one might call the Ovidian, Virgilian, Horatian, Ciceronian, Plutarchan and Senecan undergirdings to the many Shakespearean works with strong classical associations. Bate begins with a simple premise: “Storytelling was Shakespeare’s method of making sense of the world, and no stories gripped him more fully than those of classical antiquity.” Erotic obsession, madness, pagan “fame” vs. Christian salvation, the horrors of civil war, the stage as a secondary world, the symbolic import of magic, dreams and ghosts — Bate brilliantly delineates their classical origins and redeployment in Shakespeare’s work.

Why Do Lunar Satellites Eventually Crash into the Moon? [video]

Why Do Lunar Satellites Eventually Crash into the Moon?

Spacecraft orbiting the Earth have remained in space since the 1950’s and may last for centuries more, but spacecraft orbiting close to the moon can crash within weeks. The reason for this is the lunar gravity field is lumpy, with geological features making the smooth orbits of space probes distort until they hit the surface. The recent publication on the giant lunar and images taken from NASA’s Apollo, GRAIL and LRO programs.

You Don’t Need to Be Brilliant to Do Brilliant Work

Part of it was a question of ego — I’d run into this problem around the same time Csongor had. I think what happened is that people started thinking “man, this book is full of really hard concepts. And that seemed like a waste of time if I wasn’t able to amortize by that helping other people learn the same things.

Verifying Quantum Proofs with Entangled Games

Verifying Quantum Proofs with Entangled Games

In 1964, Bell showed that an entirely classical experimenter can certify that two spatially-separated parties share quantum entanglement by playing a game with them. In this talk, I will survey a recent line of research that combines Bell’s work with classical techniques from the study of interactive proof systems, to  design games that certify not just the presence of entanglement but specific, many-qubit states and operators. I will give an outline of the main techniques used as well as applications to delegated quantum computation and to quantum complexity theory, including a quantum analog of the classical PCP theorem.

Your ‘recycled’ laptop may end up in an illegal Asian scrapyard

Your ‘recycled’ laptop may end up in an illegal Asian scrapyard

“The junk comes in on shipping containers, trucked over from the port,” said Bee, a low-level administrator at an electronics scrapyard in Thailand (“Bee” is a pseudonym she provided in lieu of her actual name). When the Chinese government intensified its crackdown early last year, many e-waste brokers scattered into China’s backyard. These lawless recyclers quickly set up shop in Malaysia, Vietnam and Thailand, countries with good ports, cheap labor and lax of US recycling pile up as China restricts imports

The transnational, e-waste trade is now in total disarray — and amid the chaos, brokers are fanning out across Asia, seeking new territory to exploit the weak and pollute the skies.

GDPR After One Year

GDPR After One Year

As you can see from the mix of data and anecdotes below, it appears that compliance costs have been astronomical; individual “data rights” have led to unintended consequences; “privacy protection” seems to have undermined market competition; and there have been large unseen — but not unmeasurable! Here is the latest data on cases and fines released by the European Data Protection Board:

GDPR can be thought of as a privacy “bill of rights.” And the right to opt-out of data collection creates a free-rider problem where users who opt-in subsidize the privacy of those who opt-out.
